No, that's fine. It might actually be slightly high if anything;
this and the low boost might point to a leak somewhere.
That's not reading -boost-, it's reading manifold pressure.
1.0=same as atmospheric. 1.8 bar = almost 2x atmospheric.
With the ignition on but engine stopped, the display should read 1.0
on a stock ECU. A chipped ECU will read something like .8 because
the pressure sensor is changed(don't worry, fuel/boost/timing maps
are re-done in all of the 200q20v ECU mods sold in the US that I've
heard of.)

That's slightly low. Max is supposed to be 1.8; the test is to go
from 2k rpms to 3k rpms in 4th gear, I believe.

Did you get the "brake repair" on paper? If not, you're going to go
back in a week and say "it still does it." He's going to look at you
and suddenly have a case of amnesia. Or tell you "you need to drive
it some more...", and the week after that...
